Title: Flip-flop circuit
Inventor: KINUGASA NORIHIDE
IPC: H03K23/00
Filed: 1984-10-17
Abstract: PURPOSE:To attain stable operation even with an I<2>L as a logical circuit realizing element by constituting a binary counter having a small inter-stage delay with an FF circuit of a unit stage. CONSTITUTION:In FF circuits 1000, 2000 constituting the unit stage, an output signal of a gate 3 is fed directly to an input terminal of a gate 1 and to an input terminal of a gate 2 via two stages of inverters. Numbers 1a-15a in timing diagram show output signal waveforms of gates 1-15. The difference from a conventional example resides in the operation when an input trigger signal P is applied to the FF1000 at a time t3. That is, a pulse having a width for one gate delay time's share is given at an output of the gate 3 at a time t3', and it is caused when the output signal of the gate 3 is not applied to an input terminal of the gate 2 via gates 6, 7. Thus, the gate 2 is inhibited by an output signal of the gate 7 at the time t3' and no high frequency pulse appears at the output of the gate 2 and no malfunction is caused.
